Question 1013546
.
Find the number of subset and find the number of proper subsets of the set {31,3,16,25,8,19}
--------------------------------------------------------


This set has 6 elements.
Hence, the number of all its subset is {{{2^6}}} = 64, including the empty subset and the subset, which coincides with the master set.


See the lesson <A HREF=http://www.algebra.com/algebra/homework/word/misc/How-many-subsets-are-there-in-a-given-finite-set-of-n-elements.lesson>How many subsets are there in a given finite set of n elements?</A> in this site.


The number of proper subsets is 62 = {{{2^6-2}}}.


It does not includes the empty subset and the subset, which coincides with the master set.
